Workflow Overview

A. ProQuest uploads deposits of zip files to the content.lib.ua.edu server via ftp into the ftpaccess home directory, and notifies either Janet Lee-Smeltzer or Jody DeRidder of the upload. If Janet, then Janet notifies Jody.

B. Jody relocates the content into a directory named for the date of deposit (yyyymmdd) in the ftpaccess home directory. She then copies this entire directory to a working directory for modifications, where she unzips all the content and performs the following tasks:

extracts from each metadata file the following information:

title,

author,

year the manuscript was completed

year the degree was awarded

embargo code (if any)

calls the InfoTrack.bornDigital mysql database table on libcontent1.lib.ua.edu to find the next filenumber to assign and the InfoTrack.lookup table to determine the next persistent URL;

records the item number assigned, the PURL assigned, the author and title in these tables

inserts the assigned item number (filename, minus the extension) into a UA_identifier attribute and the assigned PURL into a UA_purl attribute within the DISS_submission field in a copy of the metadata

places this altered copy of the metadata into an PRQ subdirectory; the copy will be named with the assigned filename followed by ".prq.xml" (thus a correctly named file would be: u0015_0000001_0000023.prq.xml) to indicate this is still ProQuest XML.

copies all the bitstreams and renames them appropriately, placing them in a CONTENT subdirectory. The primary PDF will be named with the assigned filename followed by ".pdf"; subsidiary files will be numbered sequentially, with a 4-digit left-padded number attached to the assigned filename, followed by the extension. So the first subsidiary file for this file (if a jpeg) would properly be named u0015_0000001_0000023_0001.jpg, and the second (if a text file) would be named u0015_0000001_0000023_0002.txt.

creates an entry for each record in a tab-delimited xmlList.xml file which contains the following fields:

assigned filename

original filename

author

title

directory (created out of zip file name)

year the manuscript was completed

year the degree was awarded

an indicator of the existence of subsidiary files (a count)

the embargo code

date item is made available via the web

the assigned PURL

C. Jody creates a directory in the Metadata Librarian home area under etd_deposits labeled to match the date of deposit (as above: yyyymmdd). She copies the original, unzipped deposit to an ORIGINAL subdirectory. She also copies the CONTENT and PRQ subdirectories to this directory, and copies the xmlList.txt to this directory also. She then notifies the Metadata Librarian responsible for the next step.

D. The Metadata Librarian (at this time, Shawn Averkamp) works with the deposited content to create valid MODS files meeting our local profile, which include the assigned identifier and PURL, and are named for the assigned identifier with a ".mods.xml" extension.

E. The Metadata Librarian also creates valid MARC files for upload into our OPAC system, which reference the included assigned identifier and PURL.

F. She places the finished MODS in a MODS directory next to the PRQ and CONTENT directories.

G. The Metadata Librarian notifies Jody that the records are ready.

H. Jody copies the deposits to the Deposit subdirectory on the storage server, and runs a script which will move the files into the correct subdirectories for long-term storage, linking them into the LOCKSS manifests.

I. Jody extracts the filenames and embargo codes from the xmlList.xml, adds in the date the embargo starts, and calculates the end of the embargo dates. She then adds this information to a list or database entry that is checked by the periodic refreshing script.

J. The periodic refreshing script crawls through the storage directory, picks up new and modified files, checks for embargo dates not yet past, and if this raises no flags, copies the content and MODS to the web directories for online delivery. The periodic refreshing script will also note if an embargo date is past.

I. The Metadata Librarian submits a batch upload of the MARC records into our catalog system.

J. The Metadata Librarian checks the final display and access via both OPAC and digital library system to verify that no problems exist. If any problems are encountered, she contacts Jody and we work out how to fix them. :-)

K. The Metadata Librarian will batch upload the MARC to WorldCat.

L. Jody will also set up a script that will check the database on the first of each month for embargoes which are due to lift that month; this script will email Jody and the Metadata Librarians with the filename, title, author, and date that the embargo is to lift.

M. The Metadata Librarian will then prepare and upload the no-longer-embargoed-content into the local OPAC and into WorldCat.

N. Should the metadata require remediation, the Metadata Librarian add a recordChangeDate field, and will upload the altered MODS files to libcontent1 and run relocate_all.pl. This will copy the files to the live web directory (except for those under embargo) and also to a deposits directory for archival storage.
